The following lists the formulas involved and screen shots of the radiated signal from a digital Oscilloscope. • Oscilloscope used is the Tektronix TDS 544A w/TEK P6137 10x probe. • Formula for calculating the duty cycle correction: dB = 20 log (DC) Where as DC =(Max. time data is on in 100 ms ÷ 100 ms)(Max. duty cycle) “Max. Time data is on in 100 ms” refers to how many words are transmitted in 100 ms and the length of those words added together. “Max. Duty cycle” refers to the maximum bit length divided by the period of a pulse for the words recorded. • Figure A: 100ms span • Figure B: Span between each bit • Figure C: Max. On time for data. Duty cycle correction for 473T DC= [(750 μs * 12) ÷ 100 ms] = (9ms ÷ 100ms) = 90ms dB= 20 log (DC) = 20 log (90ms) = -20.915 Max. Duty Cycle Credit is –20 dB Credit. Figure C Figure AFigure B

The following lists the formulas involved and screen shots of the radiated signal from a Spectrum Analyzer. • Spectrum Analyzer used is the Hewlett Packard 8563E with HP 87405A Preamp. • Method used to determine –20dB Bandwidth as per Section 15.231 (c): CF – 20dB(∆ of points 20dB down) Where as CF =Center Frequency • Figure A: Center Frequency. • Figure B: -20dB down from center. • Figure C: -20db Bandwidth. Bandwidth data for 473T Figure A = Center @ 433.943MHz – 97.33dBuV Figure B = 433.943 MHz – 20dB delta = Delta marker @-20dB down from Center. Figure C = Marker set from Figure B @ - 20dB. = Delta marker set to as close to 0dB across Bandwidth = < 0.25% of 433.943 MHz = < 1.0848575 MHz = 17 kHz from Figure C Figure BFigure A Figure C
